A flexible coupling 10 is constituted such that a drive-side plate 11 and an intermediate plate 13 are interconnected by first connection members 14A to 14D having a rubber member in such a manner that they can move in a direction perpendicular to a direction for interconnecting pin members 15a and 15b for mounting the above first connection members 14A to 14B, and the intermediate plate 13 and a driven-side plate 12 are interconnected by second connection members 16A to 16D having the same constitution as the above first connection members 14A to 14D and arranged perpendicular to the above first connection members 14A to 14D in such a manner that they can move in a direction perpendicular to the above direction. Torque on the drive side can be transmitted to the driven side efficiently with simple constitution and the flexible coupling can be easily mounted.
